I recommend this series because the main lead is also smart.. too smart.. both focusing on communist-nationalist conflicts. there's no romance in here but brotherhood relationship. Just wanna request subbers please make an English sub for this one it is a beautiful story

Both male leads are young and their female leads always tags along. Both leads went to school to cultivate and became strong. Both female leads have mysterious/ hidden identy. Both male leads have multiple master/teachers. Villains are from certain sect/school
